1.
Heat a small to medium skillet over medium-low heat. Add the coriander seeds, cumin seeds. Toast while stirring the skillet often, for 3 minutes at least. The seeds will deepen in colour and become highly aromatic. Remove from heat and transfer to a spice grinder (or mortar and pestle)
2.
In the same skillet over medium heat, add the chickpea flour. Toast until it deepens in colour and smells toasty (~4-5 minutes). Turn off the heat and let it cool.
3.
In a medium bowl, add the ground beef along with the remaining ingredients (ground coriander mixture, toasted corn flour, red onion, green onion, green chili pepper, cilantro, garlic, ginger, red chili flakes, red chili powder, black pepper, salt, egg, and tomatoes
4.
Using your hands knead for 3-4 minutes, until you begin to see a lacy, stringy texture (resha) of the meat. The mixture should be homogenous instead of crumbly. Cover and set aside or refrigerate for up to 24 hours.
5.
Heat a cast iron skillet over high heat. Add enough oil to generously cover the bottom of the skillet.
6.
To test a piece for taste, place a piece of the beef mixture on the pan to cook, turning over as needed. Taste and adjust salt and seasoning if desired.
7.
Using oiled hands, take around 1/4 cup heaped (~90g) of the meat and form into a hearty round shape.
8.
Use your hands to shape the patties until they’re 4.5 inches in diameter and no more than 1/3-inch/3⁄4-cm thick. Place on a hot pan.
9.
Use a spoon or small spatula to flatten and spread (uneven sides add character!). Fry for 1 1⁄2 to 2 minutes on each side, using your spatula or a spoon to push oil on top of the kebab. Do not overcook. You want it crispy and charred on the outside and just cooked on the inside. (Internal temp 160°F/71°C) Flip over by lifting the kabab using a large spatula and small spatula to hold it in place.
10.
Transfer to a paper towel-lined plate. If the mixture is not binding well enough, add 1 tbsp of gram flour. Fry remaining kababs, replacing the oil if it starts to darken.
11.
Garnish with a sprinkle of ground toasted coriander and fresh cilantro. Serve immediately with mint raita and lemon on the side.
